Functionality Evaluation of System for Monitoring and Prevention of Thermal Load in Glassworks

A hot microclimate is one of the hazards that glassworkers may be exposed to. In particular, high ambient temperatures contribute to thermal load. New measures are needed to monitor this parameter in the work environment and to protect workers from related health issues. Within this research study, a new system for monitoring and prevention of thermal load in glassworks is outlined, in alignment with the Industry 5.0 vision, which is focused on humans. It consists of a monitoring part that evaluates thermal load, an actuator part that provides workers with individual cooling through electronically controlled thermoelectric modules, and a communication part for wireless communication between the monitoring and actuator parts. The functionality of the system was evaluated in a controlled environment using a microclimate chamber, a thermal manikin, and a professional wet bulb and globe temperature meter. The tests performed have proven that the system properly reacts to a potential high thermal load by activating the cooling function in the dedicated clothing with integrated thermoelectric modules. The heat flux density from the relevant thermal manikin segment reaches a maximum of 44 W/m2.
